Day 153: Frequency, Wavelength, and Toy Buggies

College-Prep Physics: Used the long slinky to generate discussion about how we might make the waves travel faster down the slinky. That lead into a dissucssion about frequency, wavelength, wave source, and wave medium. Then students used constant speed buggies, adding machine tape, markers, rulers, and a metronome app on their phones to experimentally determine the relationship between frequency and wavelength. (Sorry, I’m reposting the video from last year.) Also showed this I Love Lucy clip:

Conceptual Physics: Students finished building and testing their modified bike light circuits and began making their final annotated circuit diagrams.
